Your best bet is to have a look for similar cars for sale on Autotrader or the like - that'll tell you what other people (or garages) are attempting (note that word, it doesn't mean the cars are selling for that price) to sell for, and will thus give you a rough idea on where to price your car.

Do bear in mind that your price will realistically need to be CHEAPER than a garage - a garage has legal liabilities under the Consumer Rights Act, whereas you have no such liabilities or responsibilities.

From looking on AT, there are other similar cars for sale (not got all the options, but they don't add huge value anyway) priced at £10.5- £11k from garages. Bear in mind that garages expect to get 'chipped' down on the price, so realistically they are for sale at £10,000 or so.

Which makes your car worth, as a private sale, £9,000. Roughly.

Surely you must have realised there was a certain inevitablity to this when you bought it?.

I'm afraid you usually get very little for most optional extras once the car is a few years old, unless it's a key option eg Auto box for a Merc or air conditioning if optional!

You don't tell us the age of your car but you mention less than 3 years so I've guessed at a 65 plate. Looking at parkers for that model it shows just over £10k for a trade in and just over £11k for a private sale (30,000 miles). I've also usually found Parkers to be rather on the optimistic side as well.

Most new cars depreciate a lot in the first few years usually to about a third of their value within three years (varies between different cars) however recently diesels have been hit more than most.

You have to think of who the likely buyer is going to be. It'll have to be someone who really wants a used diesel Alfa: I think that counts as a niche market.

Yours may have been fine, but Alfas' reputation for fragility and unreliability will take a long time to go away, and of course diesels aren't exactly flavour of the month either.

The What Car tables suggest that a 3-year-old Giulietta is worth about 27% of cost when new. I'm not sure how old yours is, Guy, but if 32,600 miles is 'low mileage' it must be at least 3.

My first experience of selling back was a Suzuki 50cc motor bike fifty odd years ago, i remember the blokes exact words..i'm going to shock you...and he did, offered next to nothing. Changing cars I love but I've lost a lot of money over the years so now I try to buy a car I like and keep it much longer. Hope you get a breakthrough.
