Firstly, I've never owned a Volvo before. My wife and I are considering buying a 1994 850 Turbo wagon with 91k miles. The rear main seal is leaking, and we've been given the option to have it replaced, or get a discount to take it as-is. Common sense says to have the work done. My question is, what else should I look out for? Are there other problems likely to be lurking in the background? Is it best to walk away? With a new RMS, and assuming everything else checks out, is this a good car to buy?

Thanks in advance.
