present for husband

Husband keep on complaining about the heater of our vehicle. Sometimes it quit and sometimes it came back on. Most of the times we have to pull over just to fix it. I just glad that hubby knows how to fix in times it broke down but to be honest it needs to be taken by the mechanic to have it check and repair. Anyway, i planned on buying auto accessories like GPS systems for husband. I should have bought it as his birthday present but was thinking to get on Christmas. Hopefully i'd be able to have extra money by then.
