hi Alain, my impressions of my gt. was ok but few problems , never did like seating position front or rear seat..but loved heated seats and i had the adjustable backrest which was very good , Carbides were not my favorite with the adjustment,, my exped. i changed when brand new , for 6 inch from Qualti- piece. i did go thru 3 reverse motors before i sold it ..Exped. had better seat position and more room for pass. and easy removal with box underneath..900 was good but missed top speed a few times , gas gauge was not accurate on both.. Handling was good on exped , better than i expected with 20 x 154 .. i would order another one .. just gt had big ice buildup so u had to try to get some out at night before u put to sleep...wooden hammer and backup a few times ,, you must make sure you do not get too much ice on the air hose to the rear susp. or it will break..
