X2, whole-heartedly agree with all of this.Jason,
Maybe you want to check with them & see if they have a contact info for the original owner. You should be able to dig out some info from the original owner. And yes, you might need to replace all rubber parts and maybe all hoses if the car has been sitting around for too long. Cambelt, tensioner, pulley...If the car only has 2900 miles I doubt it if the car has gone through any kind of fluid change. So you probably want to renew all fluids too.
Also, before making a decision you should probably spend $200-$300 for a "Pre-Purchase Inspection" by a Lotus dealer or reputable Lotus mechanic that includes a leak down test & compression test. So you'll know exactly what you're buying.
At that price, you should be able to find newer models with more mileage and service records, which I would recommend. Maybe the color combination wouldn't be so desirable but I would say condition comes first.
Good Luck Hunting!
