Difficult to value a car like that - although as an aside I wouldn't describe it as Silverstone spec - Silverstone was a skinny only povery spec homologation special, really - quite desirable in its own right for its purity...but not what you've got......(anorak off....)

Although 155s are getting rarer, and odd ones are fetching - or at least asking - good money, there are many avaialable well under a grand - and very few people prepared to pay what I guess you'll need - £3K or so?

Good luck with it anyway!
