Martin I have some more info re: your questions-Personally I think the Slash is your best bet and I totally agree with Wes re: the VXL. I am not fond of brushed motors mostly because I believe brushless is a better deal. As far as the wheelie bar- I don't have one on either of my 2 Slashes and I am VXL powered w/2s 5250 and 3s 5250 Lipo's. I prefer the 2s though, the 3s is insane power! Quite honestly, I do not need all that power in a Slash. Charging the batteries? It takes me about an hour for a full charge and yes, you can charge from your car. Since I live in the US I am not sure about the availabilty for batteries there but if you check the Tamiya Mini cooper section in the Electric on-road section there are quite a few people from your area- maybe they can suggest somwhere. The VXL now comes as a waterproof combo from tower but as I said I don't know about shipping to where you are. My batt. choice is Maxamps. I get my batts, chargers from there: www.maxamps.com although there are other places and prices, these people have been very good to me. They have a great return/exchange policy. Orion is also a good choice for Lipo batt's. Duratrax is ok for Nimh and they have a good Ice charger. When you look at chargers, be sure you find one that charges both or either.
For the Slash I would recommend upgrading the Ft and Rear bearing carriers, caster blocks with RPM parts. They are cheap yet stonger than original parts. Also pick up some RPM extra pinions. The Traxxas ones wear rather quickly-RPM has those as well. Those are the main upgrades I have done to mine and it is plenty strong and fast.
Best wishes-Eric
