I respect those who stick to stock, those cars will be valuable when these become classics!
Luckily my old, high mileage example will never fetch top dollar so I don't feel guilty chaving it up 😀.
I like to be different and I also like to address any weaknesses in my cars so I'll always go the modifying route. My car is nearly perfect for my needs (scaring small children and annoying the police mainly), just needs better steering, a louder sound system and some new paint. Hopefully these will be sorted by the end of the year 🖒
