had a 2wd freetop for a couple of years now and found it brilliant,mine was lowered so has stiffer suspension and therefore doesn't suffer from high winds and fits under 2m barriers.very reliable, will cruise at 90 all day long if you want and will surprise you with its power and acceleration.It will run on straight veg oil with no conversion-so when/if the price drops its a good option, luckily I bought a few thousand litres @56p/litre
If you drive it fast you wont get amazing consumption after all its 2 ton vehicle with a biggish engine not a small car,but I have got about 40 mpg when driving at a steady 65.Another option here is to increase the wheel size so the effective gearing is a bit higher- my next project
lots of genuine low mileage ones around I picked mine up for £3.5k with 60k miles, you could get 3 or 4 for the price of a similar vw with less powererful engine look on bongofury.com for lots of info
