I got my ZR1 on Tuesday!
Sadly, the alternator went yesterday...
Never mind though - I've got a new one coming on Monday!
I love the car, and it's like new throughout, in spite of being 17 years old!
When Lotus were developing the LT5 they brought a prototype engine to my workplace (the British Internal Combustion Engine Research Institute, in Slough) for some validation testing - I fell in love with it then, and always promised myself that I would have my own one day!
So - my advice would be - buy it!
