"In my opinion, the 240 model is not easy to work on like changing water pump, heater core, heater core fan, strut & drive belts. It's doable for me because I get a tremendous amount of support here. You will find that newer cars are much easier to work. "

The 240/740/940 are almost identical to work on with a few systems better or worse based on the model but the 960 is a very different animal. Just a few of the high points:

Electronically controlled transmission
Fully modern, interference, all aluminum engine with lost spark, multi-coil ignition
Newer style fuel injection that was ODBII ready
IRS on most sedans

Mechanical knowledge and experience are transferable from one car to another. 240-specific knowledge is not. So what you learned about your heater control module, timing belt, etc. The timing belt job on a 5/6-cylinder modular engine is has very little similarity in to a B230F (recently timed a 5-cylinder manually).

FYI, the red block engines are very simple to work on by comparison to that modular platform. The 240 is a lot tighter access on many things than the 740/940 but it is still much easier to work on than almost any newer car. It is just a difference is durability/serviceability (240) verses reliability (modern Honda Accord or almost any other car). More simply put, repairing or parts swapping.
