DON'T!!!
John is one of the lucky ones. In my previous job I had a Sprinter & so did most of my co-workers. I could tell ya horror story after horror story. Repairs of like $5000 or $2000 or just what have ya after 40K miles or 58K miles. Normal maintenance is one thing. These vehicles had repair bills that had guys wanting to go postal on Dodge.
I didn't see where ya live but if ya live in the north the heater will barely be enough to keep your windows defogged & no way in hades will it keep your van warm. It will be so/so if ya have a bulkhead & only have to heat the front part of the cab, still nothing very comfy though. At least on my van that's how it was. Others have similar experiences.
Since you're going to be looking into a $35-40,000 purchase ya may want to go to a website: expeditersonline.com
Go to that site & do a search on Sprinters. You will find some people who are glad they have one. Don't get me wrong. You'll find a lot more who regret it though.
A quick rundown on my vehicle was:
Advantages:
Gas milage (though a lot of that is negated because diesel costs more than gas)
More room
Disadvantages:
Repair bills up the wazoo, at least in my case & quite a few of my friends. Plus even for things like an oil change, you can be at the dealership for several hours. The dealership pretty much has to do all repairs. When you go to buy one the salesman will tell you that you get cuts in line for repairs & to a point that's true. The thing is though, ya only get cuts in front of cars. You don't get cuts in front of other Sprinters & trust me there's a LOT of em in there for some kind of repair or another. So you're behind those & usually only one mechanic per dealership can work on a Sprinter which means you'll have to wait your turn.
very little heat/ac- that's a big vehicle to be heating as it is & w/ a crappy heater even having a bulkhead behind the seats it's not going to heat the cab very well
piss poor handling- There was a groove on a section of 275 here in Michigan than we would be 2 hands on the wheel driving only. Don't take a hand off even to take a swig of soda. That same groove I didn't even know existed until I got my Sprinter. And on a windy day, forget it.
not comfortable at all- Now comfort is a subjective thing. What's comfy for one isn't always comfy for the next. The seats are awkward & just little things like ya have to reach halfway across the van to tune the radio I found to be a hassle. I will say on this if I was doing a few 5-10 mile runs to a carpet cleaning job the seats prolly wouldn't have been a big deal. I was often putting 4, 5, 600 miles a day on the thing so it mattered to me a bit more. The radio is going to be a nuisance unless you are a very tall person.
You will find people like John who've had good luck w/ em. From the people I've talked to (other drivers when ya run into em on a shipping/receiving dock or co-workers) though, a lot more regret having bought one.
Good luck to ya,
Danny
