Having suspension problems with my 2007 Honda Accord

There's a noticeable steering wheel shake at 75 mph. It worse when going 80-85mph. I have bought new wheels, tires, replaced front struts (done at the Honda dealer), driver's side tie rod and have done at least 3 alignments and still have the problem. Also when I let go of the wheel the car goes to the left. When I drive over humpy bridges, instead of the jumping going up and down like other cars do this car jumps sideways. What could be the problem?

Which car would win?

My stock 2005 Nissan 350Z (automatic)
My friends stock 2013 Honda Accord (4 cylinder)

Straight line race for about 0.3 miles

Am I too poor to go on vacation?

I currently make 8.25$ per hour and drive a 2001 Honda accord. I have 20,000$ in student debt because I didn't finish college. I want to take my son to Jamaica. Should I? Also, I have 500$ saved for emergency money that could go toward the plane/boat trip there and back.

I got into a car accident?

So I was going to a friends house and I got into a accident, I'm fine, a little sore from falling but pretty good. According to Police report "Vehicle 1 is a 2017 Honda Civic. Vehicle 2 is a 2004 Chevrolet Suburban. Vehicle 1 parked northbound on a southbound lane in a residential neighborhood. The driver of Vehicle 1 was exiting the vehicle when Vehicle 2 collided with the Right fender. Driver of vehicle 2 claims vehicle 1 swerved into his lane and vehicle 2 could not avoid the collision. I do not suspect any alcohol/drug consumption. I estimate vehicle 1 to have sustained $500 worth of damage and vehicle 2 to have sustained $1,500 worth of damage. No citations were given." What exactly does this mean? I have full coverage, will my rates increase? Can their insurance company sue me? Am I at fault?

Added (1). Yeah I was only slightly injured from standing behind the door when the car was hit.

Dealership Advice Please

So, I had a bad experience at the El Monte Honda.

They have a summer special, a lease for the Accord LX for $109 + tax per month, for $3500 down payment with the drive-off/tax/documentation fees. I need a new vehicle and it looked very attractive and affordable so I went to the dealership to discuss it with them.

When I got there I simply told them that I'm not looking to walk away with the car today, but I'd like to know what the price would look like with all the tax included so I can be prepared to bring everything when I do come and agree to the lease. They told me they needed to do a credit check which I agreed too, and even then they wouldn't give me the paper that gave me the accurate numbers.

I went through three salesman. One of which was the director of sales and they kept sizing me up. When the director of sales finally came to talk to me, he told me that with my credit check it would be about $200, plus some pre-package stuff and the alarm… I asked why it was so high and he said it was cause of those two options. I told him I didn't need it and then he told me that he'd get rid of the alarm which got rid of the $30. I was baffled that even with all that it came out to be $170, and he didn't even give me actual crunched numbers, so I just got up and left.

I don't know for most of you but is this shady or what? Am I overreacting?

Any tips or advice to get what I want from the dealership? Anything would help.

In all of these apsects of performance which car is fastest and slowest?

Between these two fuel economy cars which is faster from a dig, roll, 1/4 mile and top end based on the torque difference?
Edit
The cars are a

1) 2006 Mazda 3i touring sedan with a 5 speed manual transmission. It has 145 ho with 132 ft lbs of torque BUT it's very lightweight.

2) 1998 Altima gxe manual 150 hp with 154 ft lbs of torque

3) 2001 Honda Accord v6 sedan model(no manual option)
200 hp with 195 ft lbs of torque

Assuming both of these cars had around 50,000 miles and of course in good condition, rank which would be the fastest and slowest.
