if it hasnt got history imo leave it alone!
my old sporting had 88k on it no history, it needeed new pistons and burnt oil by 1L every 5 miles, then the gearbox went.
my current sporting is currently on 132k with fsh, original engine and gearbox, runs brilliant and uses very little oil.
i sold my a sporting 16v for £640 with fsh and 70k on it with new cambelt and clutch and 12 months mot.
