thanks for your welcome E350, freeagent, twoxentrix and BrianW
last things first, I live in West Germany near the Belgium/Dutch border, 60 mls and 30 mls from Cologne. Maybe some race guys know the Nurburgring so called green hell, it‘s only 25 mls away.
compare consumtion is not so easy, because you calc in mpg and what I‘ve read you have to pay less than 2 us$ per gal.
If I‘m correct, 1 gal is 3.8l, 1l cost act. 1.25€ for diesel, 1.40€ for gas. Means, 6$/gal gas, or 5.3$ diesel. Depends on the savings for mpg between 5.4 gas or 7.3/6.0 diesel engine. And, actually the prices go up and down like a rollercoaster, twice a day
If I go to Italy, France or Spain, diesel is much cheaper than gas.
Mostly I will drive on a highway. The Van will be used to go to the racetracks. If I go with one bike, it will be placed inside the Van, otherwise for 2 bikes I have to use a trailer.
Pop tops are totally rare, 4x4 changes not possibel.. you live in a very good place for this customizing. All the custombuild are very restricted in germany. To buy a custom car, find a technical guy from the registration service, called TÜV, is the way to get a sportsmobile registered
but, thanks a lot for your help in advance
