Level of abuse kinda depends on the owner and what stage of it's life it's in.
Brand new - generally fawned over, kept pristine, shown at the odd car shows, with the average spirited street jaunt and track outing. Spends most of it's time parked at the end of the driveway for the neighbours to drool over and look on in envy while it's washed daily.
5-10 years old - second owner, a few dings and scratches, get's a host of tasteful, popular bolt ons. It see's a lot of car shows, but more to show off it's functional gear over form. Get's taken to the track a lot with attempts at running the best time possible out of it. Generally see's it's first sign of torque box damage at this stage.
10-20-years - bought by some teenager. ridden hard, put away wet, suffers from a sever lack of maintenance, has ridiculous stereo installed and a host of gaudy mods done to it that generally makes it run and look worse than it did in the first place. See's numerous unnecessary clutch drops and neutral over-reves and usually smells like fast food. This too is where many Fox's end their lives....and in many cases it's a mercy killing.
20+ years - generally bought by a mature enthusiast who either had one when they were new or always wanted one but could never afford or appreciate it. Hours upon hours of restoration performed (including removal of previous owners gaudy mods)...at which point it's again fawned over, kept pristine, shown at the odd car shows, with the average spirited street jaunt and track outing and spends most of it's time parked at the end of the driveway for the neighbours to drool over and look on in envy while it's washed daily.
