I feel you, i lost my exhaust recently and now my opel sounds like a lamborghini which is fun for 10 minutes but now feels shamefull and less anonymous when i come around the block and everyone knows i'm home just because the lambo sound. However i have been with it everywhere too the last 7 years and probably need to divorce it aswel as financially it's probably not worth the payment as i'm sure the mechanics will discover the other issues anyway which make it a smarter choice to just buy a new one rather than fix small issues that will cost half of the price of a new one and will equal it the next time it gets an issue.
