[RSXinfo]

I came across a 2003 Acura RSX Type S that seems good, but I don't know if I should purchase it. It is 6 speed manual, looks to be very good condition, but the one thing that is keeping me from getting it is the mileage. It has 172k miles, most of which are highway. My question is, should I purchase it? The asking price is $5999, but I don't know if the mileage makes it worth that. How much should I offer him? How many miles can an RSX get, with good care, on average? Thanks!
