I have a 2007 E320 Blue Tech, with 48,000. The warranty is about to expire and I have been approached by MB to get an extended warranty to 100,000 miles for about $3,000+.

I take good care of the car, bring it in on schedule. I am wondering if I should not set some cash aside earn intrest on it and keep going.

What is your thoughts? As you see I do a buch of driving for work and pleasue.

Thanks!
Charlie
