new engine question
 

Just bought a 1992 900S convertible auto with 70,000 mi. It has an engine knock that may require a new engine. I am planning to take it to M&M Saab in Woodstock GA and have the problem diagnosed. I have located an engine 2.1 non turbo and want opinions on who I should get to do a replacement engine or overhaul the current engine. I bought this car at a very low price, it has a very nice body and the interior is also in very good shape. It has the original window sticker $32K. Best I can figure the car was not well cared for after the original owner sold it - shame. Suggestions on the best route to go would be appreciated. Got this vehicle for my wife.
