In the end I bought the first V8 100 I looked at and picked it up on 1/1/13. Its a 53 plate face lift with a 5 speed and had done 109,000 miles. An LPG conversion, £2,000, had been done 2.5 years previously at 60,000 miles and a flashlube system was fitted at the same time. Its the best car I have owned and its now done 121,000 miles. As a tow car its awesome and running costs are no worse than the diesel, 160 miles per LPG fill in town. The suspension is fantastic and I never thought I would say it but I prefer it to my 80. Fortunate to have 3 LPG garages within 2 miles.
On the 28th its going to Charlie at Prospeed in Cardiff to have a complete stainless steel exhaust fitted as the existing is shot. Toyota wanted £3000 but Charlie is fitting it for £950 and it comes with a lifetime guarantee!!! At last it will sound like a V8. Happy days.
