Yes i know there is a difference between a KRA and a KRL....
But in practice, at least here, a well used, 20 year old KRL would be about $750-1k.
I posted the info on the KRA's to indicate the depreciation. Both those boxes are pretty new. Both, were in excellent condition and both depreciated 50%+.
Using that math a 2-5 year old KRL combo that was 9-10K new + side cab at full retail, with a current KRL 1251 top and KRL722 would be $4500-5000 mint.
Several months ago, Snappy USA had the krl 722 on promo for $3000.
This box isnt mint, and 20 years old. The seller can feel free to ask whatever he wants. BUT anything over 1k for that combo is too much in MY opinion.
