Where did the OP ask for any info on Toyota? And you're comparing this to a 'Toyota' what? Townace?
Don't advice people on things you dont fully know about. Your reply is utter rubbish .
1) Parts and repairs- There are many parts that are compatible with the standard accord, but there will be a certain amount of difficultly it matching 'Euro R specific parts like the suspension and larger break pads. Since there are only around 4 cars in SL, you wont find people stocking them. But you'll be able to source them from abroad. The Agents will support you on the running repairs- and people like Zakie (tuned i chips) have experience in tuning & repairs
2) Maintaining the car- depends on what you mean by this- this a premium car which will not fail if regular services and running repairs are attended to. And Honda's from this age are known for reliability even with high miles on them
3) Market value- Sports cars in SL tend to not hold value the same way mid range economy cars like Sunny's and Axio's do. Its not something one should expect when buying a car like this. However there is an enthusiast market for sports cars- and the right person will pay you're price if they want and like the car enough
