I can't see you driving an M3!

I feel your pain Alexis - been there myself on more than one occasion

However, as you well know, the car is worth very little in its current state (TBH, we all know that a modded Coupe running perfectly isn't worth very much either)

My recommendation would be to park the car up somewhere safe and dry and spend a year or two throwing the same money at your debt as you have done with the Coupe. Get yourself a half-decent oil-burner, such as an Alfa 156 or 147 - 50+ mpg will help with the cashflow and you won't feel the same traitorous feelings that you must have done driving that bloody Clio for all those years

The LAST thing you need to do is to make a decision in the next few days - walk away from it and see how you feel when the emotions have died down a bit - there's less chance you'll do something daft (like sell it)

Good luck
