Base warranty on SRT6 is 3/36. The extended warranty starts at purchase so a 7/70 only really adds 4 years. Each warranty firm does different things. Some are OK, some are junk. A Chrysler warranty is costly but no doubt the best. Read the fine print on coverage items. SRT6's are complicated engine-wise so make sure lots of stuff is covered there. Best to find the warranty holder and run a Google search on whether there are complaints and so forth. WarrantyDirect.com is one outfit. Don't know if they are any good or not.
