Trailer Value

Hey Guys, I have an opportunity to buy a trailer this morning for the V20, I desperately need one..lol :P The trailer I am looking at is a Magic Tilt, not sure how old it is, it is a single axle, bunk trailer with a single roller up at the very front. The trailer is in excellent condition, no rust, good carpet all the stickers are even intact. The tires, springs, axles and fenders are in ready to roll. I am not sure the single axle is what I want, but I do have 5 boat ramps within 5 miles of the house so I don't have to go very far to get in the water. A long trip for me wold be across town to a ramp at Crooked Island Sound, maybe 20 miles. The guy is asking $600.00 for the trailer and he is throwing in the 20 foot Chapparal that is sitting on it, with a partialy assembled OMC Cobra outdrive and a 6cyl motor that he claims runs. I am going to give an answer this morning so if you have an opinion abou the deal let me know. Thanks All
