Also depends on where the car is sitting outside at. There are some parts of the country that have some severe weather. There are parts of the car, in particular the Advans, that can't be subjected to the weather extremes experienced in some parts of the country. (see
Tire Rack Speaks on 14F Temp Issue).
I have also seen some dealers treat those cars like rental companies would - just spray them off or reuse towels on them and drive them hard. These may not be evident problems when first purchased but will likely create some big problems down the road.
Can you imagine - you buy a car that seems new, looks new - hardly any mileage...you drive down the road, tires warm up and
POW - tire blows, damages fender, fiberglass everywhere -
or worse, car goes out of control and injurs or kills someone.
I would be cautious...very cautious about buying a new or used Lotus that has sat on a dealer lot for any extended time - particularly in midwest to northern climates.
