That tire wear could be from too much camber, wrong tire presures, and driving style. Some of the bits that should come along with the car:
2 sets of keys, fobs, cylindrical bypass (for alarm)
2 keys for the wheel covers
Bag and glass top (with all of the hardware. You will need another, higher weatherstrip to use it)
2 floor mats
Jack, lug wrench, spare tire
All too often the seller will hold back some (or all) of these items. Maybe because he forgot, maybe as a momento, maybe to sell on E-Bay? When the car was sold new it had all of this stuff.
You should also ask if a cover is included, any extra parts, tools, bills, service history, manuals, touch-up paint, etc. Before you show ANY money ask to see the Title. Make sure it is paid off, all of the numbers agree (vin#) and it is not a salvage. If the car is due for a "C" service it can be expensive so the selling price should reflect that. Could cost as much as $5K depending on how it was cared for previously. If you do not know Lotus Esprit V-8's you *should* get someone who does BEFORE you buy it. You will certainly get them AFTER you buy it but then it is too late to negotiate the price!!!!!!!!
