Yeah its all good, sometimes you get those localised models that only go to one country. Weirdly 361PS would be a downgrade in power, can't help myself I enjoy the speed.

Sadly the mustangs are out of my price range, nothing has dropped close enough to my budget for me to even try and sweet talk a deal.

I would love a GTR but have heard horror stories of bell housing issues and all sorts on early cars, I had a 350Z as a daily for 4 years and adored that car, but was ideally looking for something able to take passengers in comfort as I do ferry people about fairly often and sometimes pretty far, would feel bad cramming them into the back of something tiny.

The insurance isn't too bad from what I have put on so far, its not super cheap but not terrible, got a fairly decent NCD bonus which does help.

But cheers for all the advice and info.

It's all good, I wasn't sure if I had missed a V8 variant, I think that would have been awesome to see personally. Looked at a Stinger before I got my current car but the stinger was a chunk more expensive.

What counts as a modern merc? And are all theb5.5 engines the same? Seen some E63 and S63 with the 5.5 biturbos that look solid but not sure if those are different engines?

How does it stack upto an F10 M5? Been looking at those as well look great but never driven one so don't know how they handle/ride.

I would recommend a BMW F10 535i 2010-2017 0-60 6sec fuel average 32mpg with as many extras as you can get. Adaptive suspension well worth going for. An excellent all round executive car

And how much will that cost to fix when it fails?.

For the OP, not sure if this is worth my saying as you seem to be much more interested in gadgets and the exhaust note. But unless you have very deep pockets, you should be focussing on the fundamental question of whether it is a good car and how reliable it is rather than how much kit you are going to get. Given the type of car you are looking at is probably going to be 10 years old or more, the kind of age that these gadgets, which looked so appealing when the car was in the showroom, may well to start failing, at great cost to you (particularly so regarding something like adaptive suspension). So i'd be actively avoiding such things in favour of a lower spec and gadget count. As for exhaust note, you can buy or have made a sports exhaust for pretty much any car if you really think it is that important that all and sundry hear you coming (personally I'd prefer to fly under the radar!).

But the most basic question you should be asking yourself is which well regarded independent specialist you have in your area and basing your car choice on that. Main dealers are going to be hugely expensive, and I'm not sure I'd trust a 'normal', albeit well regarded, local garage to something of the type you are thinking of.

One last thing, you already have an Infiniti Q50 (was that your thread not too long ago re the 2.0 turbo?), a much rarer car than pretty much anything else you are going to be looking at. Would it not be worth considering spending some money of that?. If that was you with the 2.0t, I'd be looking into what tuning could be done to the engine, and what could be done to spice up the exhaust note. It is of course never going to sound like a V6 or V8, but it shouldn't be too hard to add some voice.

Your Infiniti can hit 60mph in less than 5 seconds, how much more performance do you think you can use?. In all honesty, if the Infiniti isn't quick enough, you really need to think about taking up some form of motorsport!.

There are a couple of options, totally different in character, which would peak my interest. One has already been mentioned, the Vauxhall Monaro. Beloved of motoring journo's for its combination of old school V8 muscle car vibes (including thundering sound track), performance and dynamics. It is a fairly basic machine but all the better for it, the antithesis of a gadget and electronic trickery laden Audi, BMW, or Merc. But if looking at a Monaro, then its replacement, the VXR8 should also be looked at. Very similar under the skin, but with a 4 door saloon body, it is more spacious and practical (though be aware that there is ample space for 4 adults in the Monaro).

My other option is a car from pretty much the opposite end of the social spectrum, the Bentley Arnage!. The best can go for way more, but £20k is just about enough to get into a nice example. The most powerful 500bhp version (which isn't as quick to 60 as your Q50) would be beyond your budget so you'd be looking at the 400 or 450bhp cars. But this isn't really the kind of car that an extra 50-100bhp matters, torque is where it's at and ultimately points to its character and how you drive it. It does tip the scales at a not inconsiderable 2.6 tonnes (not far off a tonne more than your Infiniti!), so while it does handle well for its mass, it isn't a car you are going to throw about. The 400bhp version has 835NM @ 3250 rpm (your Infiniti has a maximum of 475NM from 1600rpm) and the 450bhp version has 875NM @ 3250 rpm (the 500bhp version has 1000NM @ 3200 rpm). But another major (IMO) plus point is the tyres with a sensible (for the UK's 3rd world road surfaces) depth of sidewall. But it isn't a car you should even think about unless you have a well respected independent specialist within a distance you'd be willing to travel.

I might also be tempted by an ex police car from the USA. Ford Crown Victoria or Dodge Charger maybe?. Ideally plain black or plain white, it would have to have the 'push bars' and the remote spotlights on the A pillars.

Maybe that's just me though ;-)
