That is one tidy Williams, saw the pics of the engine bay over on williamsclio and could not believe how clean it is! Rest of the car is lovely as well - no rust, must be a first for a ten year old Reno though!
I wanted one of these as my next car after my 205 GTi but made the jump to the Trophy, I'm always going to wonder now. The Williams won EVO magazines Performance Car of the Decade! The guy I bought my Trophy from said he owned a Willy back when they were new and found a drive in a Ferrari at the time slow and boring!
I hope you have many more years of enjoyment out of it, I spent a small fortune restoring my GTi but it's probably not worth all that much. Never mind, it's not all dollars and cents, enjoyed every minute in it.
Just went for an epic little drive in the Trophy and realised what it's all about, why can't the roads be clear in the day?
