Here's what I can tell you to help you decide:
* A 1987 Mercedes-Benz 420SEL is a classic car: It's likely to be a well-built vehicle with a strong engine, but it's also quite old.
* A radiator replacement can be expensive: Labor costs for a complex car like this could be high.
* Hidden problems: You should assume that a car this old will likely have other issues, beyond just the radiator.
* Research is key: Check online forums, repair shops, and mechanics to get an idea of common problems with this model year.
* Get a pre-purchase inspection: Have a reputable mechanic check the car thoroughly before you buy it. This will give you a better idea of the overall condition and any potential issues.
Consider the following questions:
* Can you afford to repair the car if other problems arise?
* How much time and effort are you willing to invest in repairs and maintenance?
* Are you looking for a reliable daily driver or a project car?
Ultimately, the decision of whether or not to buy this car is up to you. Do your research, consider your budget and needs, and make an informed decision.
