Yep, break it or sell it! get something you can enjoy whenever you get a spare second! and not have to worry about breaking it or fixing it!
Elises are simple fun little cars and the prices are getting lower and lower... or get a nice BMW coupe that the whole family can enjoy...
If you want a cheap trackcar, try and find a WELL SORTED sorted 1.9 Pug 205. Normally aspirated fun! don't get a shonky one though or you are back to where you started.
