i recently bought a 2003 rx-1 with 2000kms on it. it is in excellent condition, it has the 2004 suspension upgrade on it along with a 1 and a quarter rip saw track with only 1000kms on the track, full skid plate and a couple other things like new flap, and lower windshield. i never drove the sled since we have no snow yet hopefully we''ll have a good winter but so far i notice that the seat is kinda low. is there any upgrade for this. also is there any things else that i should look for. i bought it at a dealer so the oil is changed fresh in it for the start of this year. i read that they like oil if they are run hard so i'll have to watch that. i hope this is the last sled i have to buy for a few years. i hear good things about them getting high mileage and no much maintenance.
