Yeah, so, I'm going to have to take the same tone as VFX here, I don't hate my Warwick, but I do NOT love it anywhere near as much as my Spectors, my Stingrays, my Fender Jazz.....
Please note that all of my comments apply to the non-gloss, (satin?) finish models (e.g. German Corvette Standard, which is what I own.)
1) Resale is almost non-existent on the non-gloss models. Much worse than other basses. There's a guy with a custom shop red Corvette with flame inlays that has has been listed on the forums for over a year. Bass was $4000 new, price has dropped to $1750 with no takers for almost a year. This is due to the next item.
2) They wear out exponentially faster than other basses due to the combination of Bubinga and a satin finish. My Warwick, with standard wear, is chewed to poopie. There's a notch above the pickups where my thumb rests, there are massive gouges on the fretboard past the 24th fret due to slapping, misc dings everywhere on the body. MEC logos had worn off the pickups within the first year and both have chunks of plastic missing due to slapping. Please note, I haven't dropped this, or thrown it around....the gig bag takes a light bump and the bass ends up with a dent. I had a major panic moment when someone spilled a few drops of beer on that bass when it was only a few months old, and tbh there wasn't really a satisfactory way to clean that beer off of it. Those drops essentially soaked in instantly, with a non-satin finish I would have just wiped it off and gone about my day. TL;DR Satin finish + fairly fragile wood = not durable.
3) There's better for the price. My Corvette was between $900 and $1100 from GC in 2001. If I could travel back in time and buy a NS-CR or NS-CRFM I would in a heartbeat. Warwick, in my eyes, is REALLY expensive when you consider any of the real alternatives. TBH if I had been aware of the Spector brand there's no way I would have bought that Corvette.
4) Maintenance is a bit of a pain, again, due to the type of wood they use and the fact that they don't put a "real" finish on them. They are supposed to come with a maintenance kit (mine didn't, go GC!.) If you want the bass enough to put up with the additional maintenance, then more power to you, personally I'd prefer to just toss the bass in a case/gig bag after the show and go home.
In terms of tone; it's ok, not great. Definitely not a Fender sound, so if you want something with body that's non-traditional it's not a bad call.
I've personally been playing so long now that almost any instrument I play will sound the same once I'm done eq-ing my amp, etc. My Warwick does not stand out sonically at all in comparison to the aforementioned Spectors, Stingrays, etc.
My personal opinion re: Warwicks, after owning this one, is essentially "why bother". I can buy something I personally like better for less money (e.g. used Spector Euros) so that's the route I'm taking.
As I said though almost all of these complaints are specific to the non-gloss finish models, so YMMV, etc.
