Need your help. Just recently bought a 1997 RT10 Viper. Ever since I bought it, I've had problems. Filters, sensors, gaskets, ect. Drove it less then 10 times. After putting all this money into it the engine blew. The engine shop I have it to needs to completly rebuild and says they can do it, However I am nervous about rebuilt engines. Looking for an opinion on whether I should rebuild or buy a engine out of a salvage yard. Both are about the same cost. They are quoting me $10,000.00, does this sound reasonable for a rebuilt engine.
