You can get Koni shocks for the Marea Weekend, It's amazing the difference decent shockers make, even without lowering the car. They will cost about 2x it's market value of course, but good Q car is well worth it. I put some Jap ones on my old Tempra and over and above the outright cornering power increase (so nice to go BMW bothering) it made covering the ground along A roads at a fair clip pretty much effortless.
