You may find if you strip the car to sell you will start liking the car again and want to keep it. I find when modifying a car you can lose the character of it. I did when I sold my Octy and preferred driving it again as a std car. I haven't gone wild on my Focus for that reason alone.
For some I can imagine it's true but I am so over the moon with how it is setup & drives at the minute.
I dont know your plans but are you planning on selling the Cupra to buy a bigger family car for the missus and a track car as well. Or, selling the mods off it to fund a bigger car for the missus and using this new car to trailor your Cupra to track days.
The plan, Mr. C is to either just keep the Cupra (as is) and save to upgrade the Lupo to something that can tow.
Or
Strip the Cupra, keep the funds to one side. Sell the Cupra to pay outstanding finance (long story but been screwed over a bit by using german bank for the loan and then the exchange rate going to tits). Use the funds towards a track car. Save to upgrade the Lupo.
I can afford to pay the finance off without selling any mods but would be nice to free up some cash for both savings & spends.
Won't be making any rash decisions.
