Sorry mate but you live near london ,not a race track

I really cant see why you beat yourself up over handling. a 3 door will handle well with decent shocks and decent tyres (not 25 year old d40's) there for the trailer boys . Also a decent set of bushes would help as chances are the standard ones will be fooked
Yes the 3 door is more money and tbh they always will be . They look better and they a great car to own if you look after it .
And as for colour you are a nightmare . if you like white wait for a white one to come up for sale .
