Yesterday I went ahead and ordered the Vario XXL-R driver's seat & the Vario-R passenger's seat, both heated. Because I went with the R, they will take 8-10 weeks to get here from Germany
My wife should be picking herself up off the floor right about then...$$$...
In the mean time, I ordered the standard factory base for the driver's seat that MG posted the link to on E-Bay. Then I contacted Ray (1der) and ordered the swivel base for the passenger's seat. While talking with Ray, we discussed the possibility of using the swivel base for the driver's seat as well. I'd prefer the swivel base for the driver's seat, but have been told it won't work due to the proximity of the 4x4 shift lever. However, I can't find anyone who's actually tried it and had it not work.
So... My plan is to keep looking for someone who's done it, and if I can't find anyone, I'll go ahead and order the swivel base for the driver's seat. If it doesn't work, I'll have a swivel base to sell & I'll use the factory base. If it does work, I'll have a factory base to sell.
When it's all said & done, I'll have 4 gray Sienna seats with bases (swivel on the passenger seat) that are in excellent condition for sale. However, I do need to check with a couple of people on this forum who wanted them 2 years ago when I thought I'd be doing all this.
Is anything easy when it comes to these vans???
