"i.e. good in parts! First of all - time taken: working only bits of (most) evenings & with severely limited space (table 2 foot x 14 inches) I transfer the contents of each bag of bits into a large easy seal freezer bag, so I have as many of them as were parts bags. I then pull out of these bags only the bits as illustrated for the particular stage being built - usually from 2 to 10 or 12 parts. I have to search thro' the bags for each stage which slows things down a fair bit... but it works. This Corvette builds quite well. There are only 8 stickers, all quite large and easily placed. There are a few pictures in the manual where the build is obscured but usually it is logical & obvious anyway. Main criticism of the end result is that the rear wheels are too small for the arches, or the arches too big for the wheels, otherwise it looks ok. The remote steering feature could be better - the operating knob on back of the rear panel has too much axle poking out - a bit ugly. The "working engine" feature is gimmicky but works well. Although I still have to add the rear wing as the crucial short axle connector is missing from my set and I have no spare... a part is on the way :-) Overall this 'vette looks not bad when finished (if you like the Technic effect) and is reasonable value for money."
