Assuming it's a Gen 3, $4k is a premium price for one with 75k miles. It's not going to be in as bad a shape as a leaky gen 2 engine. Let's face it, you are paying a premium because it is from Jarco. The engine should be in good running shape. Does it have any modifications? Modifications could mean the engine was beat on. 75k miles isnt all that much for a toyota engine. Me presonally, I wouldn't pay that much, but you do get Jarco's reputation with your purchase.
