So ill start with I Have one of the earlier dbxl, I've had it going on 6 years. I bought it used. The early versions had a lot of bugs, from the feed back I get these days it seems most of them have been ironed out. I even think the chassis may be a bit thicker, but tbh I've not had the chassis flex issues some have had. The drive line (CV and shafts) remain an issue as well as the shocks. Although they seem to be a bit better now too. I haven't heard too much complaining about the bell holder melting, or diff melting issues. Any more it's nice to see that an entry level 1/5 is making so many happy. In honesty I would have bought a 5ive t if I had a do over. I know fixing and upgrading is part of the fun, but I've dumped so much coin into mine I could never part with it. But its held up well now the bugs are worked out. Just my 2c
