355 f1 spider in vegas

I am considering buying a 99 355 spider F1 until my 360 spider comes. The car is in Las Vegas and I should do a PPI.

The car has 9000 miles, titanium on black.

Can anyone recomend a good place for PPI in Las Vegas?

What should I be looking for? What questions should I be asking

What should I be paying today, and what can expect to get for trade in in early 2005.

thanks
