I am no expert, but thinking about it, the flaw in the notion of having the seat moved back with modified brackets or whatever, is the length of your legs and that isn't going to change. Imagine if you are sitting in a car with the seat set at the correct distance from the pedals, if you then have that seat moved further back by whatever means, your feet are not going to reach the pedals.

The problem here is the steering wheel, so you need to be looking at a car where the wheel has a good range of height and reach adjustment. Might be worth getting in touch with a company which modifies cars for disabled drivers, they might be able to offer some options for you.

I'm tall (6ft 4" ) and large - I find the Skoda Superb ideal (mine is 2014). Obviously it's not a high up car - although the seat goes pretty high. lot's of room upfront and it has a bigger drivers door compared to most cars. I struggle with the B pillar postion on many cars - the Superb is spot on for me. There is a good range of adjustment on the sterring wheel (reach and rake)

I'm 5'7" with an average size body and shorter-than-average legs: but I don't like the steering wheel too close to me when I'm the right distance from the pedals.

For some reason all VWs , Audis and Skodas that I've had have been ideal: all BMWs have been uncomfortable as the wheel is too close (the 2-series Active Tourer is better in this respect but the seat itself isn't comfortable.

Volvo seats are excellent but I found that there wasn't ever enough of a gap between the bottom of the wheel and the seat. If you have that problem, a flat-bottomed wheel will help.
