I would not hesitate to use Gus. He knows our cars very well and I have seen some of the nicest Pagodas in Houston at his shop.
Other options would be:
Helmut Holder (713) 683-1526 (located near 610 / 290 in Spring Branch) You may not find a more knowlegable mechanic for older Mercedes in the country. Helmut has practically taken my car apart and put it back together. I know he just replaced a windshield seal in another Pagoda. He advised that you need to be careful to get a seal that fits properly.
Sunmor Services (281) 354-2200 near Kingwood. (You have to check out Gunter's vintage racing 230SL
) See picture attached.
If you are just looking to replace the starter, and you are located in NW Houston, Larry at G.R. Auto care in Spring (281) 580-8672 on Stubner Airline near Hooks Airport can take good care of you.
Hope this helps. If you want more info send me a PM with a phone number and I will give you a call.
