Hi TL: to Dragon's credit, they'll keep going back to old kits and try to fix them. DML has put out three Firefly VCs in 1/35 scale. Their latest is #6182. 6031 is one of their earlier efforts and has a good list of problems. Of course no kit is perfect -- it's a judgement call. If you are 1) willing to ignore its inaccuracies or 2) fix its inaccuracies or 3) can get it VERY, VERY cheap and 4) don't think you'll ever treat yourself to the stunning (but expensive US$55) Tasca Firefly -- then go for it.
The VVS bogies are bogus -- from the Italeri M4A1, with incorrect (for the Firefly) upswept return roller arms. Its turret needs tweaks, its barrel needs replacement. Some soft detail -- and its hull tub is too long. For a list of fixes, go here:

Of course, if you want a quick decent build, by all means go for it. However, in this day and age of many,many accurate kits, I'd pass on old 6031 personally.
HTH, Roy
