I don't know if this would help but I just had my Sonata a couple of days ago and so far it's been great. (Drove it 50 miles so far)
Before I start though, I believe the last remodel for Sonata was 2006. 2009 is the major interior remodel.
I used to own a 2004 Elantra and I believe the HD models still uses the same engine as the XD, so power comparison should be similar. After owning an Elantra, I was leaning on buying another Elantra again, this time the new HD models.
I put a lot of research into my purchase and I came up with a 2006 Sonata. First thing on my mind was safety feature when traveling on highway. From my research, I saw that the Elantra didn't have stability control/traction control and abs. This was crucial on my list, especially after the accident in which I lost the Elantra. In addition to that, the Sonata has airbags all around.
Power-wise, I can definitely tell the difference between the Sonata and the Elantra. The V6 Sonata is much more stable on highways. Its power is undeniable (240 hp). Compared to the Elantra, with 170 hp, its difference is noticeable. It's really hard to go up above 60 mph on the Elantra but on the Sonata, it goes right up. The Sonata is also much more stable than the Elantra. When driving the Elantra on the highway, it feels like if I just suddenly tilt the steering wheel, the car would spin. On the Sonata, the steering wheel doesn't feel wobbly at all.
Price was also a huge concern for me. My budget was around 10,000 , with 12,000 maximum out the door. I was trying really hard to find a Sonata priced below 10,000 out the door. When I looked at the 2007 Elantra, almost none of them are priced less than 10,000, before tax and doc fees. When I compare the features that I would have in the Sonata and Elantra, it wasn't that hard to pick. Sonata is definitely best for your money. I do really like the interior on the new HD though. It was significantly better than the interior of the '06 Sonata, but is about the same quality as the '09 Sonata. If I could find an '07 Elantra priced below 9,000, I would probably buy it, but as it turns out, I bought the Sonata.
Finally, the Elantra uses timing belt, and Sonata, Timing Chains. With the mileage that I'm going to be looking at, the Elantra would be looking at the timing belt replacement within a year. Sonata uses timing chains, so that would cut down on about $500 that you're going to spend. (60k maintenance for Elantra is probably around $1,000 while Sonata probably around $450 tops)
Hope this helps! (IMG:
