Marshall, first off, welcome to the Viper world !! As has been posted above, these are fairly straightforward cars...IF you do your homework prior to "falling in love" with an ad, a color of Viper, or worse yet...an "attractive" price.
ln my experience and opinion, one needs to obtain a Carfax, an Autocheck, AND ask a friendly Chrysler dealer to check the vehicle's history. Then, compare those sources and look for problems or things that "don't add up".
The next step is to consult with the local Viper owners to obtain information on the dealer, the Viper, and to see if there is an experienced, honest Viper Tech in the area to do a full inspection of said Viper...for a predetermined amount of money...which should include a formal report .
Once all of this info is reviewed, one can begin to weigh the value of the potential purchase. Keep in mind that a very high percentage of these cars have suffered accidents
Many have been tracked and/or abused. Also, many owners change oil regularly...while neglecting all other fluids required for good maintenance. Much of this latter problem is self excused because they "hardly ever drive it".
Any car this age will have needs...tires, fluids are just the beginning. I always recommend budgeting an extra $6,000.00 or more over the purchase price to get any Gen I or II up to safe, reliable, roadworthy specs.
These are fantastic cars...but, buying a good one is much better than trying to rehab a ******...unless you have a lot of experience, and a well equipped shop.
